Biography

    Research & Current Focus


    Work is actively ongoing in two main areas: (1) microeconomics of chemical production  and the chemical process industries; and (2) development of novel hydroponics-based technologies for biopharmaceutical production. We have developed new microeconomic tools for the design and analysis of chemical processes and plants and for the analysis of commodity chemical markets. A process simulation-based (bottom-up) approach has been used to derive production and cost functions for chemical processes, plants, and firms. Application of this approach to petrochemical and pharmaceutical production has yielded new valuable information regarding elasticities of factor substitution, the extent of scale economies, and the nature of supply and demand curves of chemical firms in input factor and product markets. Much of this information is  unavailable or more difficult to obtain using the conventional econometric (top-down) approach, which utilizes industrial level statistical data.

    We are also engaged in the development of rhizosecretion technologies to produce biopharmaceuticals in a state-of-the-art hydroponics laboratory with capabilities to monitor and control several environmental variables (temperature; humidity; CO2 partial pressure; light intensity, spectral quality, and photoperiod; and nutrient solution composition and pH). We are currently investigating the effects of nutrient deficiencies on the type and extent of root exudates for a few varieties of tomato plants.


    Past Accomplishments

    Work at the University of New Haven and Lehigh University has been conducted in the major area of molecular thermodynamics of pure fluids and fluid mixtures. Projects have included development of an equation of state, excess enthalpy-based mixing rules, and an activity coefficient model for correlation and cross-prediction of thermodynamic properties of halogenated refrigerant mixtures. Other applications in molecular thermodynamics have been the development of an excess Gibbs free energy model to predict phase transitions in surfactant solutions, the development of an approach to predict nonideal mixture phase equilibria from limiting partial molar excess enthalpy data, and the use of complex domain numerical methods to solve phase equilibrium problems in the critical region.
    Graduate work focused on the characterization of catalytic oxidation of metal pretreated coal chars and the effects of surface functional groups on catalytic activity of microporous carbons via the techniques of adsorption microcalorimetry, surface area measurement and x-ray diffraction. Results of these studies aided in understanding the role of catalysts in the overall gasification process and in the development of a quantitative model of chemisorption and adspecies interaction on heterogeneous surfaces.
